Expression and Clinical Significance of IGHD in Pancreatic Cancer
Gene ExpressionBackground : Pancreatic cancer is the most malignant tumor in the digestive system, with low level of early diagnosis and poor prognosis. There is a lack of high sensitive and specific molecular markers in the diagnosis, treatment and prognosis of pancreatic cancer. Objective: To explore the expression of IGHD in pancreatic cancer and its correlation with clinical parameters, and to explore its prognostic value in patients with pancreatic cancer. Methods: In this study, qRT-PCR was used to detect IGHD expression in peripheral blood. The expression of IGHD in pancreatic cancer and healthy individuals was compared. The PCR results were combined with clinical data of patients. To compare the expression of IGHD in different pancreatic cancer stages and evaluate whether IGHD expression in peripheral blood can be a potential biomarker for the diagnosis of pancreatic cancer, chi-square test was used to analyze the factors influencing the expression level of IGHD. Kaplan-Meier was used to analyze patient prognosis, and further Cox regression analysis was used to analyze the factors influencing patient prognosis and independent risk factors.
Mesothelin-targeted CAR-T Cells as a Neo-adjuvant Treatment in Patients With Resectable Pancreatic...
Pancreatic CancerPancreatic ductal adenocarcinoma (PDAC) is a cancer of grave prognosis, with only about 10% of patients alive at 5 years after diagnosis. Primary surgical resection is feasible in about 10-15% of patients with an early-stage disease. Another 30-35% of patients have locally advanced disease with invasion into major vasculature but without detectable metastases. Surgery offers a chance of cure. The introduction of adjuvant multi-agent chemotherapy has improved prognosis after surgery. In the management of patients with PDAC, the role of neoadjuvant therapy is less certain. Neoadjuvant therapy for pancreatic cancer can in theory control early systemic spread and improve rate of having no macroscopic or microscopic residual tumor (R0 resection). In the The European Study Group for Pancreatic Cancer (ESPAC-5) study, neoadjuvant combination chemotherapy did not increase rate of resection who had borderline-resectable disease but appears to improve overall survival (OS). Chimeric antigen receptor (CAR) T-cell therapy may represent a new paradigm in the treatment of pancreatic cancer. Mesothelin (MSLN) is a 40 kDa membrane protein not expressed in normal cells, but highly expressed in a variety of cancer cells, such as mesothelioma, lung, breast, ovarian, gastric and pancreatic cancer. MSLN is expressed about 80% of PDAC. There are several immunotherapies targeting MSLN for PDAC treatment, including antibody-based drugs (monoclonal antibodies, antibody-drug conjugates, immunotoxins), vaccines, and CAR-T cell therapy. The safety of CAR-T cells targeting MSLN in the treatment of cancers has also been verified in several clinical trials on lung cancers (NCT01583686, NCT02414269, NCT01355965). Professor Li Peng's group at the Chinese Academy of Science designed third generation CAR-T cells targeting MSLN and validated their use in both human PDAC cell lines, animal models, and in 4 patients with advanced malignancies. In a 42-year-old man with metastatic PDAC, the MSLN targeted CAR-T treatment led to complete response follow several hepatic artery infusion and intravenous infusion. These early cases confirmed the safety of these MSLN targeted CAR-T cells. In the current proposed feasibility study, the researcher hypothesise that Endoscopic ultrasound (EUS)-guided injection of MSLN targeted CAR-T cells into PDAC can induce a tumor response, improve rate of R0 resection and translate into better patient survival.

Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid...
Advanced Malignant Solid NeoplasmBladder Carcinoma48 moreThis phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

Pancreatic CancerChronic Pancreatitis1 moreThe Coordinating and Data Management Center (CDMC) at MD Anderson Cancer will be responsible for the coordination and data management for the Evaluation of a mixed meal test for Diagnosis and characterization of Type 3c diabetes mellitus secondary to pancreatic cancer and chronic pancreatitis (DETECT), which is part of the NIH U01 funded Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer (CPDPC). Similar to all studies that will be coordinated and managed by the CDMC, no patient enrollment will occur at MDACC. All patient recruitment will occur at external sites that are a part of the CPDPC, which are listed in the appended DETECT protocol. The data management systems, auditing, and monitoring effort are supported by the CDMC.

Obtaining Solid Tumor Tissue From People Having Biopsy or Surgery for Certain Types of Cancer
Colorectal NeoplasmsGastric Neoplasms3 moreBackground: - Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: - To collect tissue samples for use in studying new ways to treat tumors. Eligibility: Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: Before their procedure, participants will have a small blood sample taken. Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.
New Biomarkers in Pancreatic Cancer Using EXPEL Concept
OncologyThe investigators recently engineered a novel biomarker discovery approach that is non-destructive and fully compatible with OMICS profiling as well as routine clinical procedures (5). The latter approach - termed EXPEL - mines the interstitial tissue fluid that is the richest source of soluble, undiluted and uncontaminated biomarkers. The method notably gives access to proteins, metabolites, RNA, DNA and exosomes, thus enabling holistic biomarker discovery. Owing to its non-destructive nature, EXPEL provides for the first time both clinicians and researchers with the opportunity to analyze identical material. The investigators hypothesize that the conservation liquid used to collect cells and biopsy after endoscopic ultrasound for pancreatic biopsy could contain the tissue secretome and permit a comprehensive OMICS analysis of PDAC (all stages confounded) by using a "modified EXPEL" procedure. These are ideal conditions for EXPEL approach that will additionally to finding novel biomarkers also shed light on complex network of cancer cell-stroma interactions.
